The United States Sign Council (USSC)

Since even before the beginning of recorded history, signs have served mankind with one of its most important and easily understood means of communication.

Today - as our environments become increasingly more complex - the need for direction, guidance, and information by means of adequate sign systems has never been more critical.

TheUnited States Sign Council is dedicated to providing an educational resource for the sign industry and it the largest Association of independent Sign shops in the world.

I am member of the USSC for many reasons, but the most important is the rock-solid information gleaned from years of research the Foundation has done about free-speech issues, and community regulation.  This knowledge is of supreme value to my clients, who need to know EXACTLY what kind of results they can expect to get from their signs - whether they are spending $1000 or $100,000 - and what kind of conditions they may encounter to get the best results that Signage offers.

Signs are mankind's oldest and still most direct form of visual communication. In the contemporary environment, they are used for guidance, orientation, place mapping, locational awareness, information, advertising, and market specific promotion.

Although their use is universal, an understanding of precisely how they function to serve the needs of our high speed, high energy environments is critical to assure that the messages they convey are clearly visible and readily understood.

It is to the accomplishment of these ends that the research programs of the United States Sign Council Foundation are undertaken.

United States Sign Council has  been dedicated to providing an educational resource for the sign industry, and is now the largest association of independent sign shops in the world.

(4) SIGN VISIBILITY, Effects of Traffic Characteristics and Mounting Height (64p)
Through use of computer simulation and mathematical models, the significant sight line blocking of low mounted ground signs is documented. Charts illustrate the degree of sight line blockage in varied traffic flow scenarios. Pennsylvania Transportation Institute, Pennsylvania State University 2003. Clickhere to order.

(5) TRAFFIC SAFETY STUDY, An Examination of the Relationship between Signs and Traffic Safety (80p)
Examines the relationship between the presence of signs and traffic accidents through an intensive mile by mile analysis of the New Jersey Turnpike, one of the most highly traveled roads in the United States. Essentially, a thorough statistical analysis relating sign density to accident density concluded that roadside signs have no statistical relationship to the occurrence of accidents. An additional study involving the relationship of accident data to the existence of an animated sign at a highly congested urban intersection indicated the same uncorrelated relationship between the existence of the sign and accidents rates over a two year period.

(6) ENVIRONMENTAL IMPACT OF ON-PREMISE SIGN LIGHTING, With Respect to Potential Light Trespass, Sky Glow, and Glare. (26p)
Addresses the actual and perceived effect of varied types of illuminated signs on the dispersion of light in the nighttime environment, concluding that on-premise signs have minimal effect when current norms of measurement for light trespass, sky glow, and glare are employed. Pennsylvania Transportation Institute, Pennsylvania State University, 2004. Click here to order.

(7) RELATIVE VISIBILITY OF INTERNALLY AND EXTERNALLY ILLUMINATED ON-PREMISE SIGNS (24p)
Examines differences in both visibility and legibility between internally illuminated and externally illuminated (including dimensional) on-premise signs. Extensive day and night field tests now confirm that internal sign illumination, on average, provides 40% greater visibility and 60% greater legibility than that provided by external sign illumination.

A research based approach to sign size, legibility, and height. Amply illustrated with tables, charts, and mathematical formulate designed to facilitate the calculation of sign letter height and copy area, negative space, overall sign size, and sign height as functions of the speed of travel utilizing the application of such factors as message size, message scan time, viewer reaction time and distance, and copy area; all presented in easy to understand language and simple tables or formulas.

(13) ON-PREMISE SIGNS: THE IMPACT OF ZONING REGULATION ON SITE PERFORMANCE (36p)
A pioneering effort to categorically establish the link between adequate on-premise signs and business success. In a study of 88 mass retailers, representing over 68,000 retail sites throughout the United States, the study clearly demonstrates a straight line relationship between business performance and adequate on-premise sign size, height, location, color, and position, documented by charts and first person interviews. In one telling criteria alone, for example, on-premise signs were adjudged to represent 91.6% of the potential for a retail site’s performance! United States Sign Council, 2005. Click here to order.

(14) ON PREMISE SIGNS: DETERMINATION OF PARALLEL SIGN LEGIBILITY AND LETTER HEIGHTS (20p)
Provides legibility values for signs parallel to a motorist's point of view which are inherently more difficult to read than perpendicular signs which are mounted directly in front of the motorist. Based on current research, the study provides a mathematical model that makes it possible to calculate the additional letter heights necessary to provide for adequate parallel sign legibility. This model can easily be applied to the current USSC Legibility Standards and Legibility Index (See 11 above, United States Sign Council Best Practices Standards for On-Premise Signs) so that letter heights developed for perpendicular signs form the basis for the larger letter heights necessary for parallel signs under similar roadside conditions. The publication offers formulate for calculation of the parallel letter heights as well as easy-to-use letter height lookup tables for many typical parallel sign scenarios.
